Etymology[ edit ] The phrase, originally from Latin "ipse se nihil scire id unum sciat" is a possible paraphrase from a Greek text see below. It is also quoted as "scio me nihil scire" or "scio me nescire". See also Apology 29d, where Socrates indicates that he is so confident in his claim to knowledge at 29b-c that he is willing to die for it.
Nor has anyone so far pointed a finger at the monks of Grottaferrata. Unfortunately, some writers including Jonathan Knight of the New Scienctist and Frederico di Trocchio in L'Espresso have interpreted the information that way, and thus indirectly implicated Prof.
Lessing, the author of our article, as being the source of such speculation. The reader is invited to judge for him- or herself whether Prof. Lessing is making such claims in the following texts.

From the chronology of disclosures and in part circumstantial evidence, it is now becoming clear that we are dealing with a recent forgery. Thus, for example, the basic two-wheeler concept on which all bicycles are based is attributed to Karl von Drais, a civil servant with a background in technology acquired at the University of Heidelberg in Germany.
Even before this conference was initiated in by Nicholas Clayton to replace such myths by serious historiography, our French delegate Jacques Seray had been able in to destroy the non-steerable two-wheeler myth created in France in the s and generally accepted thereafter.
This is also confirmed by a comparison of the pictorial bicycle evolution taken from the standard Italian book on history of technology[ 6 ] and from Marinoni, Ref. Catalogues of exhibitions and books where Marinoni was not involved demonstrate a conspicuous absense of the bicycle sketch e.
In what follows, I will concentrate on the bicycle sketch alone. This may account for the different durations given for the restoration period: While Marinoni talks of ten years, between and presumably to include dismantling of the album for the Paris exhibitionthe director of the Biblioteca Ambrosiana in Milan specified the restoration period as until An American in Madrid Nine monks had already been working on the restoration of the Codex Atlanticus for one year at Grottaferrata when sensational news electrified the press worldwide in Jules Piccus, a Bostonian Romanist, had accidentally discovered two albums of Leonardo notes and drawings in the National Library of Madrid when ordering something else.
These were called Codices Madrid henceforth. The news[ 9 ] was accompanied by a sample page Fig. Now we have a whole collection of true chain-drives and sprocket wheels. In case we should be in any further doubt, attention is called to the little drawing at the bottom, where a complete assembly is masterfully sketched.
He especially recommended their use in preference to ropes for lifting heavy loads. He did not, however, seem interested in exploring the use of chains to transmit motion.
An identical chain drive appears in the bicycle sketch put into the Codex Atlanticus. At the time of this lecture, the printing of the bicycle sketch was irrevocably underway in the Italian original of The Unknown Leonardo Ref.
Or is there another reason to withhold disclosure of a seemingly sensational discovery for four years or more?
Marinoni never gave the details, nor the date of his discovery. Also it is the experience of this conference that jingoism befalls those with greying temples rather than young people. The bicycle sketch became known worldwide through the popular three-volume set The Unknown Leonardo in Nando de Toni, former member of the Commissione Vinciana, wrote the following letter to the editor: Whoever had the opportunity to take away, bring to Florence, or send back from Lugano by mail, sheets of Leonardo, robbed from the Ambrosiana, was very well able at different times to poke fun at the descendants by drawing that rudimentary bicycle.
To pretend to be a result of the times of Leonardo it certainly did not need to have the fenders, the chain cover, the brakes, the headlight, the bell and the rear reflector. It was sufficient to leave the idea of pedals, of multiplication, of chain transmission, of the seat, and of the handlebars, even when it is obviously not working in the end.
According to de Toni, this should have concerned sheet No. To raise the value of his prey, the thief should have sketched a bicycle on it, believing that one would regard any scribble, however senseless, as the work of the universal genius and forsighted Leonardo da Vinci.
What a foolish thief had indeed expected to be able to imitate Leonardo this simply? Other sheets never left the Ambrosiana, and sheet was at the time of the theft already in Grottaferrata for restoration, since the Codex was brought there in parts.
Another member of the Commissione Vinciana, Anna Maria Brizio, art historian at the university of Milan and coauthor of The Unknown Leoardo, was interviewed[ 20 ] by the monthly magazine Panorama: How can one be sure that in years of migration the sheet had not fallen in the hands of an extemporaneous draftsman?
To solve the question, it remains only to consult the experts: Firstly, we are not certain that the sheet has not fallen into the hands of a hobby drawer during its year migration.
Secondly, the bicycle was drawn with a different ink than Leonardo used for the fortification on the front side of sheet But the journalist did not know that the sheet was in the codex in and that the forger could have been only one of the restorers or the first scholars concerned with the project possibly even the undersigned.
And like in the famous case of the Piltdown Man, we always have the option that Marinoni was the uninitiated discoverer of what was done by a different forger or forgers.About This Quiz & Worksheet.
